Wherein, the turning-in-place sensor can be arranged on the base 14 to detect the turning angle of the rotary disc 13, so as to obtain the turning angles of the first turning part 11 and the second turning part 12. For example, when the detected rotation disk 13 is smaller than the set turning angle, the turning motor 157 is caused to continue to rotate to reach the preset position, thereby implementing closed-loop control, ensuring accurate positioning of the first and second turning sections 11 and 12.

Disk 13 is connected to shaft 163 so that disk 13 is constrained to rotate about the axis of shaft 163. The telescoping rod 157 can be extended and retracted to change the distance between the two ends, i.e., the distance between the turntable 13 and the base 14. The expansion and contraction force generated by the expansion link 157 generates a torque with respect to the rotation shaft 163, thereby driving the rotation of the rotation disk 13. Because the motion trajectories of all positions on the rotating disc 13 are circular arcs, the joint of the telescopic rod 157 and the rotating disc 13 moves with the rotating disc 13 in a circular arc manner, and therefore, two ends of the telescopic rod 157 are respectively in rotating connection, so that the telescopic rod 157 can adjust the inclined posture to follow the rotation of the rotating disc 13.

Wherein the linkage mechanism 23 is linked by a change in the load of the floating disc 21, whereby the electrical connector 22 can respond and interface with the battery pack 4 in time. The power for moving the electric connector 22 comes from the gravity of the battery pack 4, and no external drive is needed, which is beneficial to simplifying the internal structure of the charging device.
